洞塞间距对多级洞塞消能影响的数值模拟研究
Numerical Simulation on the Effect of Distance Between Plugs on Multi-plug Energy Dissipation
摘要
Abstract
The distance between upper plug and lower plug affects the energy dissipation capacity of multi-stage plug discharge tunnel.In the present paper,the reasonable distance between the upper plug and the lower plug in multistage plug discharge tunnel is researched by numerical simulations.Result shows that when the contraction ratio is in the scope of 0.4-0.8,a reasonable distance between upper plug and lower plug equal to or more than 5.7D would guarantee the full display of plugs in different stages.关键词
